Well-meaning professionals throughout the years have played varying roles in the use and misuse of IQ scores to either provide assistance to individuals or to pigeonhole them into learning paths for which they may be ill suited. The purpose of this course is to define “intelligence” and “adaptive behavior.” Furthermore, it seeks to detail the challenges of accurately assessing adaptive behavior and intellectual functioning, especially in measuring and interpreting IQ scores. This course is part two of three parts on this topic, all of which are based on the book Intellectual Disability: Definition, Classification, and Systems of Support from AAIDD. The ideal audience for this course includes psychologists, faculty, lawyers, physicians, service providers, special education teachers, and other disability professionals who seek information on defining, classifying, and diagnosing intellectual disability. This course contains interactive exercises and case examples that will help reinforce your learning of key concepts.
